摘　　要：设计了一种宇航用V波段同轴微波开关,用于满足高频段下微波信号切换的需求。通过设计新型绝缘支撑结构,采用过渡段精密补偿和驱动杆精密补偿的方法,降低了V波段条件下回波损耗和插入损耗,提高了开关微波传输性能。设计结果驻波比≤1.55,插入损耗≤0.9 d B,隔离度≥100 d B,并进行了样品试制和实测,在大部分频段,实测结果与设计结果基本吻合,验证了所提出的设计方法的有效性。A coaxial switch is designed to meet the requirements of V-band microwave signal switching. The microwave properties of the switch are greatly improved by a new support structure of the insulation material,and precision compensation of the overlap part and the driving pole. The design results show the switch reaches the performance of VSWR≤1. 55,insert loss≤0. 9 d B and ISO≥100 d B. The prototype of the switch is made and measured. The measure result is tally with the design and the method is proved to be credible.
